Some stats using rsync vs using tar on a file system with big files ....<br>
<br>
Server is a FreeBSD 6.2 box, 2.93Ghz Celeron with 768MB Ram., RAID10 on
a 3ware 9500Scontroller.<br>
client is a Mac pro dual/dual xeon 2.66 6GB ram<br>
source drive 94GB of media files average file size 10MB on a 250GB
SATA-300 drive.<br>
network switched gig-e<br>
<br>
tar (baseline)&nbsp; 10.7 MB/sec<br>
<br>
rsync 1st - 5.63 MB/sec (writing data on server)<br>
<br>
rsync 2nd - 10.27 MB/sec (reading data for rsync checksum compare but
checksum cache not yet written)<br>
<br>
rsync 3rd - 35.20 MB/sec (rsync with server side checksums in cache)<br>
<br>
On all runs CPU was not the limiting factor.<br>
<br>
rsync is a big win with large files on machines with enough memory and
CPU.<br>
